Code System System Code Display Definition
http://hl7.org/fhir/identifier-use    usual Usual The identifier recommended for display and use in real-world interactions which should be used when such identifier is different from the "official" identifier.
http://hl7.org/fhir/identifier-use    official Official The identifier considered to be most trusted for the identification of this item. Sometimes also known as "primary" and "main". The determination of "official" is subjective and implementation guides often provide additional guidelines for use.
http://hl7.org/fhir/identifier-use    temp Temp A temporary identifier.
http://hl7.org/fhir/identifier-use    secondary Secondary An identifier that was assigned in secondary use - it serves to identify the object in a relative context, but cannot be consistently assigned to the same object again in a different context.
http://hl7.org/fhir/identifier-use    old Old The identifier id no longer considered valid, but may be relevant for search purposes. E.g. Changes to identifier schemes, account merges, etc.

Explanation of the columns that may appear on this page:

Lvl A few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy - see Code System for further information
Source The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
Display The display (used in the display element of a Coding ). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition An explanation of the meaning of the concept
Comments Additional notes about how to use the code
